NAIL-FILE FOR TOILET USE.

SPECIFICATION forming part of Letters Patent No. 448,409, dated March1'7, 1891. Application filed August 30, 1890. Serial No. 363,501. (Nomodel.)

T at whom it may concern.-

Be it known that 1, IsABEL CAssIDY, a citizen of the United States,residing at New York city, in the county of New York and State of 5 NewYork, have invented certain new and useful Improvements in Nail-Filesfor Toilet Use; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the [0 art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

I 5 This invention relates to certain new and useful improvements intools for use in connection with manicure outfits, the especial objectbeing to provide a nail-file which shall incorporate in a single tool afile having both a con'caved and convex file-surface, the tip of thefile being formed of bone, ivory, or other like suitable material, theuse of which will not be liable'to result in injury either to the ,nailsor to the finger-tips. The use of sharppointed tools of iron, steel, orother hard metal in the treatment of finger-nails has been found to beobjectionable, in that such use has frequently resulted in injury andsometimes to serious poisoning of the fingertips from the rust which isliable to form upon the metal point of the instrument. It has also beenfound that in order to readily and perfectly trim or form the end of thenail the use of a file having both a convex 3 5 and a concavedfile-surface is necessary.

The essential object of the present invention is to incorporate within asingle instrument a nail-file which will obviate the objections abovenoted, which will present a file- 0 blade having both a concaved and aconvex surface, and which will be provided with a tip or point of boneor ivory.

To this end and to such others as the invention may pertain the sameconsists in the 5 peculiar construction and novel arrangement of parts,all as more fully hereinafter described, and shown in the accompanyingdrawings.

The invention is clearly illustrated in the accompanying drawings,which, With the let- 5o ters of reference marked thereon, form a part ofthis specification, and in which drawings Figure l is a perspective Viewof a nail-file embodying my improvements. Fig. 2 is a similar view, inwhich the point is shown as detached but in its relative position.

Reference now being had to the details of the drawings by letter, Adesignates the file, which is provided with a suitable handle B, of anysize, shape, or material adapted to the purpose. The blade or bodyportion 0 of the file is bent upon an arc of a circle, and is pro videdupon its outer or convex face with a filesurface a, and upon its concaveface with a similar file-surface b. At its free end the fileblade is cutoff at right angles to the length of the blade, and the end is providedwith a screw-threaded extension E, adapted to e11- gage thescrew-threaded opening F, formed in the base of the tip or point G,which tip is made of either bone, ivory, or other material the use ofwhich would not be likely to injure either the nails or the finger-tipsoperated upon.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

As an improved article of manufacture, the herein-described nail-file,composed of the met-allic blade A and integral handle 13, said bladebeing curved and having its faces and convex and concave edges formedwith filesurfaces, those upon the edge projecting from the faces thereofand the end formed centrally with projecting screw-threaded extension E,and a tapered ivory tip G, having screw-threaded opening F to receivesaid extension, said tip completing the cont-our of the edges and facesof the blade, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.

ISABEL oAssIDY.
